  • 최근 우리나라 건설업계는 건설기술 인력 부족, 건설노동인력 고령화, 주 52시간 근무 등 다양한 건설환경 대응 방안으로 공업화공법 활성화에 대한 요구가 증가하고 있다. 공업화주택 인정제도는 공업화주택의 품질인정과 품질 향상 유도를 위하여 1992년에 도입되었으나 현재 6개 업체만 인정을 받았고, 인정 받은 공업화주택이 건설된 실적도 전무한 상황이다. 현재 우리나라 공업화주택 인정제도는 크게 인정 및 인정 취소기준, 공업화주택 건설촉진 기준으로 구성되어 있다. 이에 본 연구에서는 공업화주택인정제도의 관련 규정을 심층분석하여, 각 규정에 따른 문제점을 도출하고, 이를 기반으로 공업화주택 인정제도 활성화를 위한 제도 개선방향을 도출하였다. 구체적인 공업화인정제도 방안으로는 현행 공업화 주택 인정 범위를 준주택까지 확대하는 방안, 공업화 주택의 성능 및 생산기준 개정, 공업화주택 활성화 지원을 위한 건축기준 완화 및 금융지원 등을 제안하였다. 향후 공업화주택 인정제도와 별도로 국내 공업화 건축시장이 활성화되지 못하는 주요 원인 중 하나인 경제성 문제를 해결하기 위해 공업화공법의 사회·경제·환경·기술적 파급효과에 대한 체계적 분석과 가시화를 통해 건설시장 패러다임을 전환을 적극적으로 유도할 필요가 있다.

  • For decades, traditional mutation breeding technologies using spontaneous mutation, chemicals, or conventional radiation sources have contributed greatly to the improvement of crops and microorganisms of agricultural and industrial importance. However, new mutagens that can generate more diverse mutation spectra with minimal damage to the original organism are always in need. In this regard, ion beam irradiation, including proton-, helium-, and heavier-charged particle irradiation, is considered to be superior to traditional radiation mutagenesis. In particular, it has been suggested that ion beams predominantly produce strand breaks that often lead to mutations, which is not a situation frequently observed in mutagenesis induced by gamma-ray exposure. In this review, we briefly describe the general principles and history of particle accelerators, and then introduce their successful application in ion beam technology for the improvement of crops and microbes. In particular, a 100-MeV proton beam accelerator currently under construction by the Proton Engineering Frontier Project (PEFP) is discussed. The PEFP accelerator will hopefully prompt the utilization of ion beam technology for strain improvement, as well as for use in nuclear physics, medical science, biology, space technology, radiation technology and basic sciences.

  • Efforts on the continued increase of local government's fiscal spending related to improving the residential environment are desirable to counter the declining phenomenon of urban decline. At the same time, however, it is also important to know how to operate limited finances more efficiently to improve the residential environment. This study aims to contribute to the rational allocation of fiscal expenditure and the creation of productive results for the improvement of the settlement environment. To this end, this study analyzed the efficiency of financial expenditure related to the improvement of the residential environment in 225 local governments nationwide. The relationship between financial expenditure and residential environmental performance was also measured and the CCR, BCC and SBM models were used to measure efficiency. The analysis showed that most local governments need to scale back their fiscal spending related to improving the government environment. In addition, it was required to prepare feasible spending plans by bench-marking the processes of residential environment improvement projects in areas such as Haman-gun, Jongno-gu, Seoul, and Seocho-gu, which are considered to be under efficient operation.

  • This study deals with the procedure of safety improvement, productivity increase, and tact-time reduction through setting up the system about preventive maintenance. Actually, it is hard to establish and carry out preventive maintenance, even though we recognize the importance of the system concerning time, cost, labor, and so forth. In this study in the viewpoint of cost we are for achieving maximum efficiency by change and reduction of planning process adapted to the special work group. At first we briefly will mention the kind, the necessity, and the concept of preventive maintenance, and then divide the equipment used in the assembly line into the two whether it is necessary or not by way of estimating the breakdown loss, comparing with general establishment of preventive maintenance and modifying it to the case. At the second step we will establish the operation system of plan management related to production and quality in the special case. Check period and category will be set by dividing the assembly equipment into LCL and Focus in the third step. The forth step will contain the operation procedure in detail. And then we must make check and repair record periodically. Finally, on the basis of the record the selection of checking of significance will be conducted. This results in safety improvement, tact time reduction, and productivity improvement.

  • The effect of weld improvement on the corroded fatigue life of welded structures was investigated. Toe grinding, TIG dressing and weld profiling were used as the geometric improvement methods. Fatigue tests under the corroded condition in artificial seawater were carried out to investigate the corrosion fatigue behavior of API 2W Gr.50T steel plate produced by POSCO. The test results in weld improved conditions were compared with those in as-welded condition. The test results were also compared with the design curves in UK DEn Class F. Corroded fatigue life of weld improved specimens was longer than that of as-welded specimen. Especially, the corroded fatigue life exceeded the mean SN curve in air of UK DEn Class F.
